Henry Farny had two sketches featured in the September 30, 1865, issue of Harpers Weekly, pages 620-621. These images and the entire issue can be seen at archive.org: https://archive.org/details/harpersweeklyv9bonn/page/620/mode/2up?q=farny
According to an article in the June 11, 1909, issue of the Times-Star, pg4, col4-6, these Farny images were the first ones to be published in Harpers:
I remember the Turnfest of 1865 very well indeed. I was only a boy then [he was 17], but it struck me that there was something picturesque and unusual, as well as of interest to the people of the country at large, so I made a couple sketches and sent them to Harper’s Weekly. They were immediately accepted, although I have never sent them any work before. It resulted in me getting many commissions from Harpers and was a great help to me. I do not remember much about the Turfiest now after the lapse of forty-four-years, bu I recall that the street scene showing the procession was sketched ash the corner of Hamilton road, now McMicken avenue, and Vine street. The full-page scene showing the Turners engaged in their exercises was sketched at Parker’s Grove.
The image from Pg. 621 can also be see at the Cincinnati County Library, https://digital.cincinnatilibrary.org/digital/collection/p16998coll57/id/446
